31:23 Every thing that may abide the fire, ye shall make [it] go through the fire, and it shall be clean: nevertheless it shall be {h} purified with the water of separation: and all that abideth not the fire ye shall make go through the {i} water.
(h) The third day and before it is molten.
(i) It shall be washed.
31:19-24 The Israelites had to purify themselves according to the law, and to abide without the camp seven days, though they had not contracted any moral guilt, the war being just and lawful, and commanded by God. Thus God would preserve in their minds a dread and detestation of shedding blood. The spoil had been used by Midianites, and being now come into the possession of Israelites, it was fit that it should be purified.
